I had a rusty brake line blow out and I have two lines feeding to the rear load sensing proportioning valve. I took everything out then cut, spliced, and flared some new 3/16" line from the two lines and went directly into the proportioning valve on the rear axle. I never ever ever could get a pedal after bleeding and bleeding the brakes. I replaced the MC and (after bench bleeding and) bleeding again still no pedal. I noticed I had bubbling in the back of the reservoir while pressing the pedal. That made me wonder if my fix was jankey. I then wondered if maybe one of the lines from the load sensing valve runs back to the abs and I attached the lines to the wrong connectors on the LSV. Any ideas? Does it sound like this could be the issue? Unfortunately at this point I ripped out all the brake line starting at the connectors behind the passenger side tire. I'm going to start over and have a clean line running from there. Also, for what its worth, I have a bypass line going from out one connector into the other behind the tire and I have a great pedal (but only front brakes needless to say). From the brake piping diagram on Nissan Parts Zone it looks like the top line goes to the top connector on the proportioning valve and vise versa, but I have no idea at this point. I should have taken picture before destroying it. My bad. Any help or links I may have misses would be appreciated...thanks!

I got some conflicting info on order. I did pass rear, driver rear, pass front, driver front. I didn't know the LSV itself had a bleeder until today. That also may have been a factor, but I read some people skip bleeding the LSV, so I'm not sure. Thanks.
